ABSTRACT:
A video recording and reproducing apparatus with photoelectric image camera in which a color signal processing circuit of a recording system is simplified. For recording, a luminance signal and a chrominance signal are produced in accordance with an image being picked up through a photoelectric transducer. The luminance signal is angle-modulated, while a carrier signal having a lower frequency than the standard carrier signal is directly modulated with the chrominance signal, whereby a chrominance recording signal equivalent to a signal obtained by a frequency conversion of the standard carrier signal to a low frequency band is obtained and added with the angle-modulated luminance signal to be recorded. Upon reproduction, the angle-modulated luminance signal undergoes angle-demodulation to be converted to a reproduced luminance signal, while the color (chrominance) recording signal is frequency-converted to a high frequency band to be reproduced color signal. The reproduced luminance and color signals are added together to obtain a reproduced color video signal.
